WebHowever, if we create a barrier between those two populations, this stops gene flow. They can no longer move between the two populations and genetic information is no longer shared. As a result, the two populations slowly diverge in terms of their evolution. Eventually they are no longer able to reproduce because they have become too different. WebGoogle Classroom.
